Definitions

  • This disclosure relates to a load bearing system for a residential structure of a type that comprises facade panels mounted to an exterior of the structure.
  • the load bearing system has particular use in the construction of single- storey, multi-storey and duplex-type structures.
  • the load bearing system helps to facilitate modularisation of the construction process.
  • Load bearing systems for buildings and other structures are fundamental in providing structural integrity to support various loading conditions, e.g. wind loads, live and dead loads, etc.
  • the load bearing system can include columns and beams which are spaced about a foundation of the residential structure.
  • the arrangement and configuration of the columns and beams can be determined by the design requirements of the structure.
  • the columns and beams may be desirable to position the columns and beams to suit certain styles of residential structure, for example, open plan kitchens, balconies, etc.
  • a load bearing system for a residential structure is not limited to use with a residential structure, rather it is particularly suitable for a residential structure.
  • a residential structure may include a single- storey residential structure, a duplex-type residential structure or a multi-storey residential structure.
  • the load bearing system can help to facilitate modularisation of a construction process for the residential structure.
  • the load bearing system can comprise two or more structural load bearing columns.
  • Each column can be for mounting to a foundation of the residential structure in spaced relation to the or each other column.
  • the columns can be spaced from each other at predetermined locations on the foundation.
  • Each column can comprise a periphery defined by hollow- section members and one or more internal bracing elements extending between the hollow-section members.
  • the hollow- section members can, for example, be rectangular-hollow- section members, circular-hollow- section members, etc.
  • the hollow-section members can be roll formed, hot-rolled, etc. (e.g. from steel such as mild steel).
  • Each column may be prefabricated to be transported to a building site.
  • the number and position of the columns to be used at the building site may be predetermined/pre-calculated.
  • key components of the system may be prefabricated, and their arrangement at the building site may also be predetermined/pre-calculated.
  • the load bearing system can further comprise at least one beam extending between and connected with respect to in-use upper ends of the two or more structural load bearing columns.
  • the beam can, for example, be connected to a given column and can be located at the upper end of the column.
  • the beam can be connected to the upper end of the column, being distal to a lower end of the column, which can be mounted directly or indirectly to the foundation.
  • the number and position of the beams to be used at the building site may be predetermined/pre-calculated.
  • the beams may also be prefabricated, or they may be cut to size on site.
  • the load bearing system can further comprise at least one cladding (i.e. facade) panel mounted to extend between the foundation of the residential structure and the at least one beam.
  • the cladding panel can take the form of a facade panel. Such a panel can both enclose and enable decoration/completion of the residential structure, such as by being provided with various finishes (e.g. externally and internally of the facade panel).
  • the cladding (facade) panels may again be prefabricated.
  • the cladding panels can be fabricated with main weatherproofing features already integrated such that, when mounted between the foundation and the beam, the installed panels weatherproof the residential structure. When installed, the cladding panels can define an external wall of the residential structure. The ability to install cladding panels in this way can provide a rapid way of constructing an external wall of a residential structure.
  • the load bearing system can, at least to some extent, modularise construction of the residential structure.
  • the cladding (facade) panels can be mounted. This can, for example, be enabled by lifting (e.g. by a crane) the panels into place.
  • the structure is essentially weatherproof, and works can commence on the interior of the residential structure.
  • the columns, beams, cladding (facade) panels, etc. can be prefabricated. Their sizing and configuration can also be predetermined. The requisite number and sizes of such components, along with any additional mounting accessories, can be packaged and may be supplied as a kit. The package/kit may be transported for installation at a worksite. Installation instructions may be supplied (e.g. in printed and electronic formats). The delivered components can then be rapidly installed onsite (e.g. at a preformed foundation, such as a concrete slab).
  • each of the two or more columns of the residential structure may be elongate.
  • Each column may have a depth such that it is able to be arranged, in use, inboard of the at least one cladding panel.
  • each column may be arranged towards an internal space, being the space defined by a perimeter of the foundation.
  • the at least one cladding panel can be located at a front face of the column, for example, at an external side of the column relative to the internal space.
  • the at least one cladding panel can be located at a side face of the column, for example, at an external side edge of the column relative to the internal space.
  • each column may be such that it can be incorporated into a wall of the residential structure.
  • the depth of the column may be such as to enable the wall of the residential structure to substantially conform to typical wall thicknesses for residential structures.
  • each column can provide a load-bearing function whilst being ‘hidden’ into a wall of the residential structure. This contrasts with prior art columns which are often either exposed, or they have a dimension such that, when incorporated into a wall of the residential structure, the resultant wall around the column is thicker than conventional and/or thicker than a remainder of the wall.
  • the load bearing system may further comprise internal cladding.
  • the internal cladding may be a type of autoclaved aerated concrete (AAC), such as an AAC panel, suitable for an interior space of the residential structure.
  • AAC autoclaved aerated concrete
  • the internal cladding may instead comprise plasterboard, timber, or other suitable internal cladding materials.
  • the internal cladding may be mounted with respect to a back (or internal) face of each of the two or more columns (i.e. a face of the column that faces inwardly of the residential interior space).
  • the internal cladding may be mounted with respect to a side face (e.g. a side edge) of each of the two or more columns.
  • the internal cladding may be mounted with respect to the columns via a fixing system.
  • a known fixing system can employ a series of spaced ‘top-hat’ elongate profiles secured to span between adjacent columns, and to which the internal cladding may be fastened (e.g. by suitable fasteners, such as self-tapping screws, etc.).
  • each column may become incorporated into a wall of the residential structure, such as a wall that is defined by the at least one cladding (facade) panel and the internal cladding.
  • the column can be located (e.g. sandwiched) between an externally facing facade panel and internal cladding such as AAC, plasterboard, timber, etc.
  • the internal cladding is installed on site, although the amount and location of the internal cladding to be used at the building site may be predetermined/pre-calculated.
  • each column can enable internal cladding to be mounted (e.g. directly) to the column; this can simplify use of the system.
  • traditional residential structures typically require a framing system to be constructed along the perimeter of the foundation. Whilst the framing system can provide a load-bearing function separate to columns, the framing typically extends along or adjacent to each side of the foundation.
  • the internal as well as external cladding is then mounted to the framing along each side of the foundation.
  • the internal cladding can be connected to each of the discretely spaced load bearing columns, and to span between the columns. For example, suitable cladding-mounting battens can be employed that span between adjacent columns.
  • the external cladding i.e.
  • the present system can avoid a traditional residential framing system, and the time and cost associated with the use of such framing systems.
  • the residential structure may comprise at least four columns for mounting to the foundation in spaced relation to each other.
  • each column may be arranged to correspond to a comer of a room in the residential structure.
  • the at least four columns may be arranged such that they can be incorporated into four walls that form a room of the residential structure.

  • each truss column 12 is configured for mounting (e.g. by being bolted such as via chemical anchor bolts) to a foundation 14 of the residential structure.
  • the foundation 14 can take the form of a reinforced concrete slab, etc.
  • the truss columns 12 are spaced apart from each other according to the design requirements of the residential structure.
  • discretely spaced truss columns 12 can be arranged around a perimeter of the foundation 14, and intermediate, spaced truss columns 12’ can be arranged internally of the foundation 14.
  • the intermediate truss columns 12’ can support roof/ceiling spans for an overlying roof or upper storey of the structure. As explained below, the intermediate truss columns 12’ can support beams that extend across the foundation (e.g. partially or fully from one side to the other). As also explained below, the intermediate truss columns 12’ can be incorporated into internal walls of the residential structure (e.g. by being sandwiched between internal cladding mounted to front and back faces of the intermediate columns). Likewise, the perimeter truss columns 12 can be incorporated into external walls of the residential structure (e.g. by being sandwiched between external and internal cladding mounted respectively to front and back faces of the perimeter columns).
  • the perimeter and intermediate truss columns 12, 12’ can support fixing systems for internal cladding that can define spaces, e.g. rooms, partition walls, etc. within the residential structure.
  • the intermediate columns 12’ can be configured to support external cladding panels (i.e. facade panels) on their front and back faces.
  • the residential structure 10 may include e.g. an atrium whereby the internal walls (and intermediate columns) are ideally configured with external facade panels that are normally employed at the perimeter of the structure (i.e. for outdoor or semi-outdoor use).
  • each truss column 12, 12’ (hereafter designated ‘12’) comprises a periphery in the form of an outer frame 16, the frame being defined by hollow- section members 18.
  • Each truss column 12 has an elongate, rectangular form (i.e. when viewed in front elevation).
  • Each truss column 12 also comprises one or more internal bracing elements which, in this embodiment, take the form of a single ‘zig-zag’ truss brace 20 that extends between the hollow- section members 18 as shown. In other embodiments (see e.g. Fig. 18 described below) the internal bracing can take a different form.
  • Fig. 8 illustrates the truss column 12 orientated horizontally (i.e. not in an in-use orientation) for the purposes of clarity/description only.
  • the hollow- section members 18 for the top and bottom chords of the truss column 12 comprise rectangular hollow-section members 18a, whereas the hollow- section members 18 for the long sides of the truss column 12 comprise square -hollow- section members 18b.
  • the square-hollow-section members 18b define vertical members 56.
  • the rectangular hollow-section members 18a define top and bottom chords 58.
  • Each of the vertical members 56 and top and bottom chords 58 are mitred at their comers and are typically fixed together at the mitre -joints by a welded connection.
  • the truss brace 20 is typically formed from a single, circular- section rod which extends between the opposing vertical members 56 and the top and bottom chords 58. As above, the single rod is bent so as to extend up from the bottom chord 58, between the vertical members 56 in a zig-zag configuration, to connect to the top chord 58. In this way, the internal bracing 20 defines a plurality of apexes 60 at each of which the truss brace 20 is welded to the vertical members 56. Distal ends 62 of the truss bracing 20 are bent so as to be arranged parallel with the top and bottom chords 58. Typically, the distal ends 62 are welded (or riveted, etc.) in position at the top and bottom chords 58.
  • the internal bracing 20 defines column 12 as a ‘truss’.
  • each truss column 12 has a high load- bearing capacity for a relatively small footprint.
  • the use of hollow- section members for each of the top and bottom chords and long sides of the outer frame 16, along with the truss brace 20 that extends between the hollow-section members 18, means that an elongate but comparatively ‘shallow’ (i.e. reduced depth/thickness) column structure can be manufactured, supplied and used. As explained below, this advantageously allows each truss column 12 to be incorporated into a wall of the residential structure 10 (be that an externally or internally arranged wall).
  • each truss column 12 has a side-to-side width ‘W’ that is greater than a front-to-back depth ‘D’ thereof.
  • W side-to-side width
  • D front-to-back depth
  • having a depth that is substantially smaller that the width allows the truss column to be incorporated and ‘hidden’ into a wall (i.e. the dimensions of the wall do not need to change in order to accommodate the truss column therein).
  • This allows each truss column to perform its load-bearing function whilst concealed within a wall, providing structural integrity to the residential structure without occupying floor space (i.e. space that a larger, pre-existing and typical load bearing column would require).
  • each truss column 12 can be seen as having a ‘slender’ form whilst still be able to meet load-bearing standards.
  • the bottom-to-top height of each of the top and bottom chords 58 is greater than the side-to-side width of the vertical members 56 (dimension ‘M’).
  • This configuration is beneficial for supporting the column under bending load, such as dynamic and e.g. wind loads.
  • the relatively larger bottom to top height of the chords 58 also assists in the distribution of stress under bending loads.
  • a number of beams 22 are arranged to extend between upper ends of the discrete, spaced truss columns 12.
  • Fig. 1 shows the beams 22 connected together into a framework (i.e. ‘portal framework’), but in Fig. 1 the framework of beams is shown in an ‘exploded’ (i.e. separated) arrangement from the multiple spaced truss columns 12.
  • Figs. 3 to 5 & 15 show the framework of beams in their connected arrangement with respect to the multiple spaced truss columns 12.
  • the beams 22 serve to tie together the upper ends of the multiple spaced truss columns 12, thereby providing one or more ring-like, load-bearing and securing structures at the upper ends of the truss columns.
  • the so-arranged beams 22 can provide a supporting framework for a roof or for an overlying (upper) storey(s) of the residential structure 10, including for the floor thereof.
  • the so-arranged beams 22 can define a portal frame that is self- supporting and does not require e.g. propping.
  • truss columns 12 In use, as soon as the truss columns 12 have been fixed in situ to the foundation 14 (see Fig. 14A), upper ends of the truss columns can be connected together by the beams 22 to create a rigid framework structure. Such a structure is self- supporting and is now ready to support cladding panels in the form of facade panels 24, as well as internal cladding, as set forth below.
  • Figure 1 also shows how the arrangement of beams 22 forms multiple ring-like structures throughout the residential structure 10.
  • beams 22 arranged around the perimeter of the residential structure form a main ring-like structure.
  • Internal beams 22 combine with the perimeter beams and/or other internal beams to form smaller ring-like structures that generally correspond to internal walls and rooms located within the perimeter of the residential structure.
  • the beams are, in general, directly connected to an upper end of at least one of the truss columns 12. However, in some cases (see e.g. beam 22’ in Fig. 1A), one end of a beam (22’) may be connected indirectly to a truss column (12’) via another beam (22”).
  • both ends of a beam may be connected indirectly to spaced truss columns.
  • a number or all of the beams can connect indirectly with respect to the truss column upper ends (e.g. such as to be offset from each upper end) and so as to accommodate other structural elements.
  • the beams 22 take the form of Parallel Flange Channel Section (PFC), i.e. a C-channel beam.
  • the beams may have other forms such as a Universal Beam (UB), i.e. I-beam.
  • UB Universal Beam
  • the number and types of beams used throughout the residential structure can be strategically designed, selected and located in terms of the room layout and load bearing requirements. That is, the number and location of truss columns 12 and beams 22 is selected and optimised towards minimising the overall weight and size of the column-beam structure as much as possible, but without compromising load-bearing capacity.
  • I-beams provide better load bearing capacity than an equivalent C- channel beam, however, I-beams are heavier than the equivalent C-channel beam. In this way, the weight of the structure can be reduced by generally employing C- channel beams and minimising (or eliminating) the number of I-beams used. In some situations (e.g. long spans), one or more I-beams may be employed.
  • a single beam 22 is connected with respect to two truss columns 12.
  • This simple arrangement could be employed to define a stand-alone wall.
  • a beam 22’ can extend between two spaced apart beams 22” and 22”’, wherein the two spaced apart beams are connected respectively to upper ends of truss columns 12’ and 12”.
  • the beam 22’ that extends between the two spaced apart beams 22”, 22”’ is also connected ‘with respect’ to the two spaced apart beams, but as set forth above, need not be directly connected to the truss columns.
  • one end of beam 22’ connects only to an end of beam 22”, with the beam 22” then being directly connected to the truss column 12’.
  • An opposing end of beam 22’ connects to an end of beam 22”’ but can also be connected to the truss column 12”. Many other permutations are possible.
  • a room R in the residential structure 10 comprises at least four truss columns 12.
  • Fig. 1 shows a ground floor/lower storey in which multiple truss columns 12 are mounted to the foundation 14 in spaced relation to each other.

  • each truss column 12 is thin enough such that, when incorporated into a wall, it does not increase the thickness of the wall when compared to either a non-load-bearing wall, or a wall that provides only a minimal load-bearing function. This can eliminate the need for columns to be manufactured and/or installed that are separate to the wall frame itself. Typically, such known columns have a much larger footprint and/or weight than an adjacent (e.g. timber or steel) wall frame. The use of truss columns 12 can thereby eliminate the use of known columns and e.g. timber or steel wall frames.
  • Figure 2 also illustrates the position of adjacent facade panels 24’ (i.e. once installed). It will be seen that the installed facade panels 24’ are either flush with an edge 21 of the foundation 14 and/or are flush with an outer face of a beam 22 (e.g. when the panels 24 are being mounted to an overlying storey in a residential structure).

  • the foundation 14 of the residential structure is first laid (e.g. poured) to form the ground floor.
  • the foundation 14 is typically formed of concrete, but a timber or steel framework construction can be employed instead.
  • a plurality of truss columns 12 i.e. ground floor columns
  • Some of the truss columns 12 are mounted at a perimeter of the foundation, whereby the columns are just inset from an edge 21 of the perimeter.
  • Other truss columns 12’ are mounted at intermediate locations of the foundation 14, whereby the columns are spaced away from edge 21 and are arranged closer to a middle of the foundation.
  • the columns are arranged according to a predetermined, pre-planned layout.
  • each of the ground floor truss columns 12 having been secured to the foundation 14, the beams 22 are now connected with respect to upper ends of the truss columns using by a bolted connection (e.g. 34 and via brackets 66).
  • the beams 22 are prefabricated and are typically pre- sized and pre drilled with apertures to correspond to apertures 70 in the truss columns 12.
  • each of the 22 beams typically extends between the upper ends of adjacent truss columns 12 (i.e. from one truss column to the next).
  • the resultant mounted beams 22 define a plurality of closed perimeters (i.e.
  • a plurality of truss columns 12 for the upper storey 48 are next mounted to the underlying beams 22 of the lower storey 46.
  • Stabilising brackets 66 can be employed as required, or the truss columns 12 can be ‘free standing’ via the bolted connections 120.
  • the upper storey beams 22 are then connected with respect to upper ends of the truss columns using a bolted connection (e.g. 34 and via brackets 66). Again, as shown in Fig.
  • the beams 22 are arranged to define a plurality of closed perimeters (i.e. ring-like, closed-loop arrangements) at the upper ends of the upper storey truss columns 12 to provide a supporting framework for upper storey walls and for a roof at location 50 of the residential structure.
  • closed perimeters i.e. ring-like, closed-loop arrangements
  • the upper storey 58 can also employ roof ties 19 (e.g. in locations where floor to ceiling windows, etc. are to be employed).
  • the roof ties 19 ‘close the loops’ of the upper storey framework to provide structural support to the residential structure 10.
  • the roof to be located at 50 is a flat roof, however, the roof can be a pitched roof or other variation.
  • an upper storey floor 44 is next installed to extend between the beams 22 and truss columns 12 located at the junction of the upper and lower storeys 48, 46. It is noted that, at this stage of the construction, the roof can be installed before the floor 44 is installed (e.g. if it is desirable to have a protective cover for the floor 44).
  • formwork decking 52 can mounted to extend between the beams 22 that form a perimeter of each room. Concrete for the floor 44 is then poured.
  • the decking 52 can be propped by conventional means to support the load applied by the poured concrete as it cures.
  • a framework-type floor support structure can be installed at 44 (e.g. of timber and/or steel) and then conventional flooring systems (e.g. floor boards and/or panels) can be installed.
  • the roof can be installed at 50 after at least the floor support structure has been installed or after concrete pouring. In either case, installation of the roof helps to facilitate ‘lock-up’ of the residential structure at an early stage of the construction process.
  • Figs. 21F, 21G and 21H illustrate a sequence of mounting of external cladding in the form of a plurality of facade panels 24 to the perimeter of the residential structure 10.
  • a plurality of facade panels 24 are first installed in sequence to the framework for the lower storey 46 (i.e. ground floor).
  • the lower storey facade panels 24 are each mounted to the sub-sill 32F located at the foundation 14, and then the sub-head 30 is located in place and mounted with respect to the beams 22 via the fascia beam 35, as previously described.
  • the lower storey facade panels 24 are each lifted into place such as via an on-site crane.
  • the facade panels can be lifted by a person from the inside of the residential structure.
  • Fig. 21G shows the fully installed facade panels 24 for the upper storey 48.
  • FIGs. 21F, 21G and 21H are schematic, in that they depict the panels 24 being installed vertically, i.e. in a sliding motion from the roof to the foundation. Typically, this is not the precise installation method used to install the panels 24. A specific method for installing the panels is described below with reference to Fig. 22.
  • fittings such as windows 28, are incorporated into the walls of the residential structure.
  • the windows 28 can be integrated (i.e. prefabricated) into the facade panels 24, or can be arranged and mounted between two facade panel portions.
  • Facade panels 24 can be omitted to accommodate e.g. doorways 64, curtain windows 29, curtain walls, etc.
  • fascia panels 54 can now be mounted to locate between the lower (ground) storey 46 and upper (first floor) storey 48 to conceal the fascia beam 35 and beams 22. Fascia panels can also be mounted to locate between the upper (first floor) storey 48 and the roof at location 50.
  • the method of mounting the fascia panels 54 is as outlined above.
  • each truss column 12 becomes incorporated into (i.e. hidden within) a respective wall of the residential structure (e.g. between the facade panels 24 and internal cladding 26 - external wall; or between two internal cladding panels - internal wall; or between two facade panels 24 -extemal/internal wall).
  • doorways 64, floor-to-ceiling windows 21, curtain windows, curtain walls, etc. can be mounted at locations where cladding panels have been omitted.
  • the facade panels 24 can be preconfigured or treated post installation with various surface finishes, including e.g. a variety of rock-like materials, plaques, plate, metal, timber, glass, polymer, marble-like finishes, cement render, stucco, etc.
  • the facade panels 24 are installed according to the following methodology. Firstly, the panel 24 is brought towards the perimeter of the foundation 14 and an upper end is moved beneath an overlying beam 22 such that the upper end is tilted towards an outside of the structure 10. A lower end of the panel 24 is mounted, i.e.
  • the panels 24 When installing panels 24 in a single storey structure, or in an upper-most floor of a multi-storey structure, the panels 24 are installed with substantially the same methodology described above, primarily differing in how the upper end of the panel 24 is mounted to the structure. In this case, i.e. when installing a panel with respect to the roof, once the panel 24 is nested in the sub-sill 32F and moved back towards the overlying beam 22, the panel 24 is brought into contact with the L- bracket 35S mounted to beam 22.
  • the panel 24 can be mounted e.g. screwed or bolted to the bracket 35S so as to secure the upper end of the panel to the residential structure.
  • the truss columns 12 and beams 22 of the upper storey 48 can be arranged in the same or a similar way to the truss columns 12 and beams 22 of the lower storey 46. As illustrated in Fig. 15, some of the truss columns 12 and beams 22 can be located in different positions, for example, when differently shaped and configured rooms are required on the upper storey 48. Further, some of the beams 22 and truss columns 12 can be omitted or orientated differently between the lower storey 46 and upper story 48. This can allow for different configurations of e.g. rooms, corridors, stairwells, etc. to be formed at each of the floors/storeys.
  • the load bearing system as described above, including truss columns 12, beams 22 and facade panels 24, together with the additional components (e.g. external supports 29, fascia panels 54, brackets 66, etc, can be prefabricated and pre-sized such that they can be transported as a smaller (e.g. flat) package for installation at a worksite.
  • the components can be supplied as a kit, included with mounting elements such as bolts, tools, instructions for assembly onsite, etc.
  • the abovementioned kit having releasable mountings, e.g. bolted connections, can be disassembled so as to deconstruct the residential structure.
  • at least some of the components, e.g. beams, columns etc, of the structure can be recycled/reused in a further residential structure.
  • the residential structure can be moved to a new site.
  • a load bearing truss column can be supplied that comprises internal bracing elements arranged in a zig-zag formation as described above, together with bracing elements arranged horizontally, as described above.
  • each of the sub-head 30 and sub-sills 32, 32F can be mounted to the beam and foundation, respectively, by a releasable (e.g. bolted) connection.
  • the sub-head 30 and sub-sill 32 can be fixably mounted to the beam 22 by e.g. a welded connection.
  • Each of the sub-head 30 and sub-sill 32 can be releasably mounted to the truss columns 12 by bolted connections.
